Lzx32.sys is a file associated with the Rustock.B Trojan.http://www.symantec.com/security_response/...-99&tabid=2
You can reference this bleepingcomputer post BleepingComputer.com/Security/HJT Logs
to aid in cleaning it off using http://www.uploads.ejvindh.net/rustbfix.exe
Since you are unable to get into Windows normally without a blue screen, you'll need to download these files on a seperate computer, and burn them to a CD or save them to some other type of media. Then, try to log into your laptop in Safe Mode.
Restart your computer
After hearing your computer beep once during startup, but before the Windows icon appears, tap the F8 key continually;
Instead of Windows loading as normal, the Advanced Options Menu should appear;
Select the first option, to run Windows in Safe Mode, then press Enter.
Choose your usual account.
If you aren't able to log into Safe Mode then post here so people can give you other suggestions on things to try.
If you are, then run the fix programs while in safe mode, then restart your computer and see if that stops the blue screen problem. Afterwards I would suggest running HighJack This and posting the log in case you have anything else that needs to be cleaned off.
